Exemplary embodiments relate to an automotive sensor integration module.

Discussion of the Background

As technology becomes more advanced, various sensors, electronicdevices, and the like are also provided in a vehicle for userconvenience. In particular, research regarding an advanced driverassistance system (ADAS) has been actively conducted for users' drivingconvenience. Furthermore, the development of autonomous vehicles isactively under way.

The ADAS and the autonomous vehicles require a large number of sensorsand electronic devices to identify objects outside a vehicle.

Referring to FIG. 1, in order to detect objects in front of a vehicle, acamera, a lidar, a radar sensor, etc. are disposed in front of thevehicle, but are disposed at different positions respectively.

Although objects should be identified on the basis of detection resultsdetected by sensors at the same timing in order to improve performancein detecting objects, it is not easy to synchronize object detectionsensors because the sensors are disposed at different positions.

The above information disclosed in this Background section is only forunderstanding of the background of the inventive concepts, and,therefore, it may contain information that does not constitute priorart.

FIG. 2 is an outside view of an automotive sensor integration moduleaccording to an exemplary embodiment of the present invention.

An automotive sensor integration module according to an exemplaryembodiment of the present invention may include a plurality of devicesand sensors for detecting objects outside a vehicle to acquire safetyinformation related to vehicle driving. In this case, the objects mayinclude a lane, another vehicle, a pedestrian, a two-wheeled vehicle, atraffic signal, light, a road, a structure, a speed bump, a geographicalfeature, an animal, etc.

The lane may be a driving lane, a lane next to the driving lane, or alane along which an opposite vehicle travels. The lane may include leftand right lines forming a lane.

Another vehicle may be a vehicle that is travelling in the vicinity of ahost vehicle. The other vehicle may be a vehicle within a predetermineddistance from the host vehicle. For example, the other vehicle may be avehicle that is located within a predetermined distance from the hostvehicle and precedes or follows the host vehicle.

The pedestrian may be a person in the vicinity of a host vehicle. Thepedestrian may be a person located within a predetermined distance fromthe host vehicle. For example, the pedestrian may be a person on asidewalk or the roadway within a predetermined distance from the hostvehicle.

The two-wheeled vehicle may be a vehicle that is located in the vicinityof a host vehicle and moves using two wheels. The two-wheeled vehiclemay be a vehicle that has two wheels and is located within apredetermined distance from the host vehicle. For example, thetwo-wheeled vehicle may include a motorcycle or a bicycle on a sidewalkor the roadway within a predetermined distance from the vehicle.

The traffic signal may include a traffic light, a traffic sign, apattern or text drawn on a road surface.

The light may include light from a lamp in another vehicle, light from astreet lamp, or light emitted from the sun.

The road may include a road surface, a curve, and a slope such as anupward slope or a downward slope.

The structure may be an object which is located around the road andfixed onto the ground. For example, the structure may include astreetlight, a roadside tree, a building, a power pole, a traffic light,a bridge, etc.

The geographical feature may include a mountain, a hill, etc.

Meanwhile, the objects may be classified into a moving object and astationary object. For example, the moving object may conceptuallyinclude another vehicle, a two-wheeled vehicle, a pedestrian, etc.,while the stationary object may conceptually include a traffic signal, aroad, a structure, etc.

As such, it may be desirable to use various sensors and devices toaccurately identify various objects around a vehicle.

In order to accurately identify objects outside a vehicle, an automotivesensor integration module according to an exemplary embodiment of thepresent invention may include a plurality of different types of sensorsand devices. In addition, the automotive sensor integration moduleaccording to an exemplary embodiment of the present invention mayinclude at least one sensor and device of the same type.

Referring to FIGS. 2 and 3, the automotive sensor integration module 100according to an exemplary embodiment of the present invention mayinclude an infrared camera 12, an optical camera 11, a lidar 14, and aradar 13 as a sensor to identify an object outside a vehicle. Theautomotive sensor integration module 100 according to an exemplaryembodiment of the present invention illustrated in FIG. 2 is exemplarilyshown to include an infrared camera 12, an optical camera 11, a lidar14, and a radar 13 as a sensor in order to identify an object, but isnot limited thereto. In addition, the automotive sensor integrationmodule 100 according to an exemplary embodiment of the present inventionillustrated in FIG. 2 shows two infrared cameras 12, one optical camera11, two lidar 14 s, and one radar 13, but the number of each sensor issuggested only for illustrative purposes and is not limited thereto.

Referring to FIGS. 2 and 3, the automotive sensor integration module 100according to an exemplary embodiment of the present invention mayinclude a circuit board, an infrared camera 12, a camera 11, a radar 13,and a lidar 14. For example, the automotive sensor integration module100 according to an exemplary embodiment of the present invention mayinclude a circuit board on which an infrared camera 12, an opticalcamera 11, a radar 13, and a lidar 14 are disposed and mounted.

The optical camera 11 designed to acquire outside images of a vehiclethrough light and recognize objects, light, and people around thevehicle may include a mono camera, a stereo camera, an around-viewmonitoring (AVM) camera, and a 360-degree camera. The optical camera 11has advantages of being able to detect colors and accurately classifyobjects compared to other sensors, but has a disadvantage of beingaffected by environmental factors, such as darkness, backlight, snow,rain, fog, etc.

The radar 13 may detect an object on the basis of a time-of-flight (TOF)method or a phase-shift method through electromagnetic waves, and detectthe location of a detected object, the distance to the detected object,and the relative speed. The radar 13 has an advantage of being capableof long distance detection without being affected by environmentalfactors, such as darkness, snow, rain, fog, etc., but has a disadvantageof failing to detect an object, made of an electromagneticwave-absorbing material, for example, a steel structure such as a tunnelor a guardrail, and thus, being unable to classify objects.

The lidar 14 may detect an object on the basis of a TOF method or aphase-shift method through laser light, and detect the location of adetected object, the distance to the detected object, and the relativespeed. The lidar has advantages of being less affected by environmentalfactors such as darkness, snow, rain, fog, etc., efficient in long- andshort-distance detection due to high resolution, and objects are able tobe simply classified, but has a disadvantage of failing to measure thespeed of objects immediately.

The infrared camera 12 may acquire outside images of a vehicle throughinfrared rays. In particular, the infrared camera 12 may acquire outsideimages of the vehicle even in darkness at night. The infrared camera 12has advantages of being capable of long distance detection and beingcapable of distinguishing living things from objects without beingaffected by environmental factors, such as darkness, snow, rain, fog,etc. but has a disadvantage of being expensive.

As such, in order to accurately classify and identify external objectsaround a vehicle regardless of environmental factors, the advantages anddisadvantages of each sensor must be combined. Therefore, the automotivesensor integration module 100 according to an exemplary embodiment ofthe present invention discloses a structure in which a plurality ofdifferent sensors are all disposed and mounted on a circuit board. Inaddition, the automotive sensor integration module 100 according to anexemplary embodiment of the present invention may synchronize and outputdetection results of a plurality of sensors having different operationcycles, thereby having an advantage of classifying and identifyingobjects more accurately.

FIG. 3 discloses a configuration of an automotive sensor integrationmodule 100 according to an exemplary embodiment of the presentinvention.

With reference to FIG. 3, the automotive sensor integration module 100may include an optical camera 11, an infrared camera 12, a radar 13, alidar 14, an interface unit 20, and a signal processing unit 30. Here,the interface unit 20 and the signal processing unit 30 may beimplemented as hardware or software in the circuit board illustrated inFIG. 2.

The optical camera 11 may output information sensed through light asfirst detection data C_s. The optical camera 11 may output firstdetection data C_s for each preset sensing period. For example, theoptical camera 11 may output information sensed through light as thefirst detection data C_s every 33 ms (30 Hz).

The infrared camera 12 may output information sensed through an infraredray as second detection data IC_s. The infrared camera 12 may output thesecond detection data IC_s for each preset sensing period. For example,the infrared camera 12 may output information sensed through an infraredray as second detection data IC_s every 33 ms (30 Hz).

The radar 13 may output information sensed through an electromagneticwave as third detection data R_s. The radar 13 may output thirddetection data R_s for each preset sensing period. For example, theradar 13 may output information sensed through an electromagnetic waveas the third detection data R_s every 50 ms (20 Hz).

The lidar may output information sensed through laser light as fourthdetection data L_s. The lidar 14 may output fourth detection data L_sfor each preset sensing period. For example, the lidar 14 may outputinformation sensed through laser light as the fourth detection data L_severy 100 ms (10 Hz).

Here, pieces of detection data C_s, IC_s, R_s, and L_s output from theoptical camera 11, the infrared camera 12, the radar 13 and the lidar 14may have different communication specifications. For example, the firstdetection data C_s output from the optical camera 11 may be data in aformat used in a Low Voltage Differential Signal (LVDS) communication.The second detection data IC_s output from the infrared camera 12 may bedata in a format used in a Gigabit Multimedia Serial Link (GMSL)communication. Data output from the radar 13 and the lidar 14 may bedata in a format used in Ethernet.

The interface unit 20 may convert different data formats of thefirst-to-fourth pieces of detection data C_s, IC_s, R_s, and L_s intopreset data formats. The interface unit 20 may convert the formats ofthe first-to-fourth pieces of detection data C_s, IC_s, R_s, and L_sinto a data format according to a preset communication technology amongvehicle network communication technologies.

Here, the automotive network communication technologies may include aCAN communication, a LIN communication, a Flex-Ray® communication,Ethernet, and so on. For example, the interface unit 20 may convert thefirst-to-fourth pieces of detection data C_s, IC_s, R_s, and L_s intodata according to the Ethernet communication.

The signal processing unit 30 may receive the first-to-fourth pieces ofdetection data C_s, IC_s, R_s, and L_s of the same format converted bythe interface unit 20. The signal processing unit 30 may synchronize,with a preset timing, the first-to-fourth pieces of detection data C_s,IC_s, R_s, and L_s of the same format output from the interface unit 20,and output the synchronized data to the outside of the automotive sensorintegration module 100.

For example, the signal processing unit 30 may output, as sensing dataC_ss, IC_ss, R_ss, and L_ss, the first-to-fourth pieces of detectiondata C_s, IC_s, R_s, and L_s at the same timing based on an input timingof one of the first-to-fourth pieces of detection data C_s, IC_s, R_s,and L_s. For more specific example, the signal processing unit 30 may beconfigured to receive and store the first-to-fourth pieces of detectiondata C_s, IC_s, R_s, and L_s, and output the stored first-to-fourthpieces of detection data C_s, IC_s, R_s, and L_s as the sensing dataC_ss, IC_ss, R_ss, and L_ss, if a preset time PT elapses after the thirddetection data R_s has been input to the signal processing unit 30.

On the other hand, the signal processing unit 30 may block an outputfrom a malfunctioning or failing sensor or device among the opticalcamera 11, the infrared camera 12, the radar 13, and the lidar 14 frombeing provided as the sensing data.

For example, if the optical camera 11 is determined as malfunctioning orfailing among the optical camera 11, the infrared camera 12, the radar13, and the lidar 14, the signal processing unit 30 may output only thesecond-to-fourth pieces of detection data, IC_s, R_s, and L_s other thanthe first detection data C_s as the second-to-fourth pieces of sensingdata IC_ss, R_ss, and L_ss.

Here, if the respective pieces of detection data C_s, IC_s, R_s, andL_s, of the optical camera 11, the infrared camera 12, the radar 13, andthe lidar 14, which are to be input to the signal processing unit 30 forrespective sensing periods, are not input thereto at correspondingperiods, the signal processing unit 30 may determine that a device or asensor, from which the input has not been received, malfunctions orfails, and block detection data from the device or sensor, which hasbeen determined as malfunctioning or failing, from being output as thesensing data.

FIG. 4 discloses a configuration of the signal processing unitillustrated in FIG. 3.

With reference to FIG. 4, the signal processing unit 30 may include amalfunction detection unit 31, a reference signal selection unit 32, asynchronization pulse generation unit 33, and an output synchronizationunit 38. Here, the signal processing unit 30 may receive thefirst-to-fourth pieces of detection data C_s, IC_s, R_s, and L_s ofwhich formats are converted by the interface unit 20.

Hereinafter, although, in the explanation about the signal processingunit 30, the first-to-fourth pieces of detection data C_s, IC_s, R_s andL_s of which formats are converted by the interface unit 20 are simplyreferred to as first-to-fourth pieces of detection data C_s, IC_s, R_s,and L_s, the first-to-fourth pieces of detection data C_s, IC_s, R_s,and L_s input to the malfunction detection unit 31 and the referencesignal selection unit 32, which constitute the signal processing unit30, are pieces of data of which formats are converted by the interfaceunit 20.

The malfunction detection unit 31 may determine whether or not eachpiece of the first-to-fourth pieces of detection data C_s, IC_s, R_s,and L_s is input from each sensor 11, 12, 13, or 14 to the signalprocessing unit 30, namely, the malfunction unit 31 for eachcorresponding sensing period.

For example, the malfunction detection unit 31 may check whether thefirst detection data C_s is input to the malfunction detection unit 31for every sensing period of the optical camera 11 to determine whetherthe optical camera 11 malfunctions or fails.

The malfunction detection unit 31 may check whether the second detectiondata IC_s is input to the malfunction detection unit 31 for everysensing period of the infrared camera 12 to determine whether theinfrared camera 12 malfunctions or fails.

The malfunction detection unit 31 may check whether the third detectiondata R_s is input to the malfunction detection unit 31 for every sensingperiod of the radar 13 to determine whether the radar 13 malfunctions orfails.

The malfunction detection unit 31 may check whether the fourth detectiondata L_s is input to the malfunction detection unit 31 for every sensingperiod of the lidar 14 to determine whether the lidar 14 malfunctions orfails.

The malfunction detection unit 31 may output, as failure codes M_s<0:3>,whether or not each of the optical camera 11, the infrared camera 12,the radar 13, and the lidar 14 malfunctions or fails. Here, the failurecodes M_s<0:3> may include a first failure signal M_s<0>, a secondfailure signal M_s<1>,a third failure signal M_s<2>, and a fourthfailure signal M_s<3>.

For example, if the first detection data C_s is input at the sensingperiod of the optical camera 11, the malfunction detection unit 31 mayoutput the first failure signal M_s<0> at a digital logic low level. Onthe other hand, if the first detection data C_s is not input at thesensing period of the optical camera 11, the malfunction detection unit31 may determine the optical camera 11 as malfunctioning or failing, andoutput the first failure signal M_s<0> at a digital logic high level.

If the second detection data IC_s is input at the sensing period of theinfrared camera 12, the malfunction detection unit 31 may output thesecond failure signal M_s<1> at a digital logic low level. On the otherhand, if the second detection data IC_s is not input at the sensingperiod of the infrared camera 12, the malfunction detection unit 31 maydetermine the infrared camera 11 as malfunctioning or failing, andoutput the second failure signal M_s<1> at a digital logic high level.

If the third detection data R_s is input at the sensing period of theradar 13, the malfunction detection unit 31 may output the third failuresignal M_s<2> at a digital logic low level. On the other hand, if thethird detection data R_s is not input at the sensing period of the radar13, the malfunction detection unit 31 may determine the radar 13 asmalfunctioning or failing, and output the third failure signal M_s<2> ata digital logic high level.

If the fourth detection data L_s is input at the sensing period of thelidar 14, the malfunction detection unit 31 may output the fourthfailure signal M_s<3> at a digital logic low level. On the other hand,if the fourth detection data L_s is not input at the sensing period ofthe lidar 14, the malfunction detection unit 31 may determine the lidar14 as malfunctioning or failing, and output the fourth failure signalM_s<3> at a digital logic high level.

Accordingly, if at least one or more among the optical camera 11, theinfrared camera 12, the radar 13, and the lidar 14 is determined asmalfunctioning or failing, the malfunction detection unit 31 maygenerate and output failure codes M_s<0:3> that have code valuescorresponding thereto.

The reference signal selection unit 32 may output, as a reference signalRef_s, any one among the first-to-fourth pieces of detection data C_s,IC_s, R_s, and L_s based on the failure codes M_s<0:3>. For example, thereference signal selection unit 32 may output, as the reference signalRef_s, detection data corresponding to the failure signal having adigital logic low level among the failure codes M_s<0:3>.

If a failure signal having a digital logic low level is present inplurality among the failure codes M_s<0:3>, the reference signalselection unit 32 may output, as the reference signal Ref_s, detectiondata determined according to a preset priority. If it is assumed thatthe preset priority has the order of the third detection data R_s, thefirst detection data C_s, the second detection data IC_s, and the fourthdetection data L_s, the reference signal selection unit 32 may operatein a manner as shown in the following Table 1.

TABLE 1 0: Low, 1: High M_s<0> M_s<1> M_s<2> M_s<3> Ref_s M_s<0> M_s<1>M_s<2> M_s<3> Ref_s 0 0 0 0 R_s 1 0 0 0 R_s 0 0 0 1 R_s 1 0 0 1 R_s 0 01 0 C_s 1 0 1 0 IC_s 0 0 1 1 C_s 1 0 1 1 IC_s 0 1 0 0 R_s 1 1 0 0 R_s 01 0 1 R_s 1 1 0 1 R_s 0 1 1 0 C_s 1 1 1 0 L_s 0 1 1 1 C_s 1 1 1 1 X

As shown in the above table 1, since the third detection data R_s is thehighest in the priority, the reference signal selection unit 32 mayoutput, as the reference signal Ref_s, the third detection data R_s, ifthe third failure signal M_s<2> is not at a digital logic high level.

If the third failure signal M_s<2> is at the digital logic high level,the reference signal selection unit 32 may output, as the referencesignal Ref_s, the first detection data C_s having a lower priority thanthe third detection data R_s.

In addition, if the first and third failure signals M_s<0> and M_s<2>are both at the digital logic high level, the reference signal selectionunit 32 may output, as the reference signal Ref_s, the first detectiondata C_s having a lower priority than the third detection data R_s.

If the first-to-third failure signals M_s<0> to M_s<2> are all at thedigital logic high level, the reference signal selection unit 32 mayoutput, as the reference signal Ref_s, the fourth detection data L_shaving the lowest priority. The reference signal selection unit 32 maybe simply implemented using a decoder and a multiplexer.

The synchronization pulse generation unit 33 may receive the referencesignal Ref_s to output a synchronization pulse P_s. The synchronizationpulse generation unit 33 may generate and output the synchronizationpulse P_s based on the reference signal Ref_s. For example, if thereference signal Ref_s is input and a preset time PT elapses, thesynchronization pulse generation unit 31 may generate and output thesynchronization pulse P_s.

The output synchronization unit 38 may receive the first-to-fourthpieces of detection data C_s, IC_s, R_s and L_s, the synchronizationpulse P_s, and the failure codes M_s<0:3>, and output thefirst-to-fourth pieces of sensing data C_ss, IC_ss, R_ss, and L_ss. Forexample, the output synchronization unit 38 may selectively receive andstore the converted first-to-fourth pieces of detection data C_s, IC_s,R_s and L_s provided from the interface unit 20 based on the failurecode M_s, and output the stored detection data as the sensing data C_ss,IC_ss, R_ss and L_ss according to the synchronization pulse P_s.

For example, the output synchronization unit 38 may receive and storeonly detection signals corresponding to failure signals input at adigital logic low level among the failure code M_s<0:3>, and output, assensing data, the stored detection data according to the synchronizationpulse P_s.

The output synchronization unit 38 may include a first synchronousoutput unit 34, a second synchronous output unit 35, a third synchronousoutput 36, and a fourth synchronous output unit 37.

The first synchronous output unit 34 may receive the first detectiondata C_s, the selection pulse P_s and the first failure signal M_s<0>,and output the sensing data C_ss. For example, if the first failuresignal M_s<0> is at a digital logic low level, the first synchronousoutput unit 34 may be activated. The activated first synchronous outputunit 34 may receive and store the first detection data C_s, and outputthe stored first detection data C_s as the sensing data C_ss based onthe synchronization pulse P_s.
